' Claims.

This invention relates to :e'yeshields andmore particularly it has reference-to-eye'shields of the type which embodies a frame bar and a single integral lensmember which is detachably secured to'th ebankq Y One of the-objects of my invention is to provide an-eyeshi'eld of'thetypedescribed-which will be simple in structure, embody a minimum number of parts and hence be relatively inexpensive to manufacture. ,Another objectis to provide an eyeshield having a 'lens member which may be interchanged ea-sily and without the use f tools. A "further object is to provide' an'eyeshield of the type described having improved means for attaching nose engaging pads thereto. These and other objects and advantages reside in certain novel features of construction, arrangement and combination of parts as willhereinafter be more fully described and pointed out;in :the appended claims. I

A preferred embodiment of my invention is shown on the drawings wherein I0 indicates, generally, an eyeshield having an integral plastic transparent lens member ll. Extending along the top edge of the lens member H is the frame bar [2 which has on its under side a groove [3 in which is seated the upper edge of lens member H. The lower edge of the lens member H has a re-entrant or cut-away portion M which is adapted to fit over or straddle the nose Of the wearer.

The lens member H is held in its grooved seat 2 terminate in 'rearwardly extending substantially horizontal parts [8 which carry the nose pads l9.

The clamping member 15 is-made of resilient ma-. terial so that the resilience urges the arms H laterally away from each other and thus holds the parts l8 against the edge of the re-entrant portion L4,.as'shown inFig. 3.

The eyeshield may be disassembled readily by urging together the ends of the arms 11 andthen unhooking the part 16 from the top of barul2.

The ;frame bar I2 may be made .of any suitable material such as plastic. The usual temples 2| arehingedly carried by the temporal ends of the frame bar 12. Thelens member H may befmade.

of either .clear or tinted transparent material- .In themodification .shown in Figs. 5-8, there is provided :an integral transparentplastic lens member 31 having on its temporal edges the proe jections 32 which fit into mating :notches p33 formed on the inner side wall of the :framebar 3A. The :upperedgeof lens member. .3liszseated in the groove- 35 formed in the under smears:

bar' 34 which is r'formed of a plastic-material which is resilient. In attaching the lens member 3% to the bar 34, the projections 32 are fitted into the mating notches 33 and the central part of the bar 34 is then flexed upwardly s that the top edge of the lens member 3| snaps into the groove 35.

The clamping member 36 provides additional means for holding the lens and frame bar together and also affords means for supporting the nose pads 31. The clamping member 36 is made of a resilientmaterial and has the hooked or reversely bent portion 38 which is hooked over the top of frame bar 34. Extending downwardly from the hook 38 and along the rear surface of lens member 3| are the two diverging arms 39 to the lower ends of which are attached the horizontal arms or parts 40 which have rearwardly extending parts carrying the nose-pads 31. The

clamping member to the eyeshield, the lower ends of arms 39 are flexed together, the hooked part 38 is hooked over the top of bar 34 and when the ends of arms 39 are released, the horizontal parts 40 will be positioned under the notches 42 and held there by the resilience of the arms 39.

3 The usual temples 43 are pivotally carried by the temporal ends of the frame bar 34.

From the foregoing, it will be apparent that I am able to attain the objects of my invention and provide an improved eyeshield which is simple in structure yet efficient in operation. The parts may be readily assembled and the lens member may be inserted or removed without the use of tools. Various modifications can, obviously, be

made without departing from the spirit of my invention as pointed out in the appended claims.

I claim: 1. An eyeshield comprising an integral transparent lens member adapted to protect both eye's of the wearer, said lens member having onit's" lower edge a re-entrant portion adapted to straddle the nose of the wearer, a frame bar ex- 4 terial and with the arms extending downwardly in diverging relationship so that the horizontal portions of the arms are held, respectively, under the horizontal notches by the resilience of the member to efiect clamping action and thereby detachably hold the lens member in the groove. 4. An eyeshield comprising an integral lens member adapted to protect both eyes of the wearer, said lens member having on its bottom edge a re-entrantportion adapted to straddle the wearers nose, a frame bar extending along the upper edge of the lens member, the under side of the bar having a groove in which is seated the upper edge of the lens member, holding means hooked over the top of the bar and engaging the edge of the re-entrant portion for holding the lens member in the groove and additional holding tending along the upper edge of the lens member, Y

the under side of the bar having a seat in which the upper portion of the lens member is positioned and a clamping member holding the lens member in said seat, said clamping member being hooked over the top of said bar and in engagement with the edge of the re-entrant portion on the lens member whereby the lens member is detachably held on the frame bar. Y

2. An eyeshield comprising an integral transparent lens member having on its lower edge a reentrant portion adapted to straddle the nose of a wearer, a frame bar extending along the upper edge of the lens member, said bar having on its under side a groove in which the upper edge of the lens member is seated, a clamping member holding the lens member in said groove, said clamping member having a part hooked over the top of the bar and a pair of arms extending downwardly from said part and along the lens member and thence horizontally to engage the edge of the reentrant portion, and a nose engaging pad carried by each of said arms.

3Z-Thel construction described. in claim '2 in, which there-entrant portion'of thelens member has a horizontal notch on each of its'sides, and

the 'clamping member is formed of resilient mameans at the temporal portions of the lens member comprising mating projections and notches on the respectively adjacent temporal parts of the lens member and said bar.

5. In an eyeshield having an integral lens member provided with a re-entrant portion adapted to straddle the nose of the wearerand a frame bar extending along the top of the lens member and having a seat in which the upper edge of the lens member is positioned, the combination of a clamping member for holding the lens member in the seat, the clamping member having a part hooked over the top edge of the bar member and other parts engaging the edge of the re-entrant portion in the lens member whereby the lens member is detachably secured to the frame bar.
